remarkable sight in Afghanistan. Tonight president Obama calling it a milestone. Across the country men waiting to cast their vote and the women waiting in their own lines, too. Millions proudly showing off their fingers stained in purple after voting. The millions who defied threats from the Taliban to vote. Reporter: They stood for hours. Millions braving the rain. The democracy is spreading all over the world. Reporter: From women in burcas to 89-year-olds. All I want is a peaceful Afghanistan he told us. A gesture of defiance from the Taliban. I'm very happy. 25-year-old woman put it in a message from the entire country to the militant. You are the loser and we are the winners. Reporter: That win is historic. 7 million out of 12 million eligible voters cast a ballad, a 58% turnout equal of that to the U.S. Elections in 2012 and to the biggest victory of all. 35% of all voters were women. Today's votes cap off months of campaigning with extremely tight security. Stakes couldn't be higher. All three candidates say they want American troops to stay in the country something president Obama has asked for. As we speak, millions of votes are being counted part of a long process that could take several weeks.
